V wardly. The blank is much narrower above These and other objects and advantages the portion 6 and is formed into a semi-cyof the invention will be fully set forth in lindrical or trough-shaped portion '7, the the following description made in connec open side of which extends toward the direc- 90 tion with the accompanying drawings, in tion of flange 3. The base flanges 3 and 5 which like reference characters refer to the are provided with an aperture, preferably same parts throughout the diiferent views, circular, axially alined with the trough and in which, shaped portion 7. At the upper end of the portion 7, the sides thereof form parallel lugs 8 and are apertured to receive a transversely extending nutted bolt 9 shown as having a grooved button head. A vertically extending wire or rod trough-shaped are extended to 10 is received in the trough-shaped portion to 7 so as to be slidable therein and may be clamped in any desired position of adjustment by the bolt 9. As shown in Figs. 1 and 2, this member 10 may consist of an ordinary Wire nail or spike. layer is to be of such thickness that such a nail or spike of suflicient length is notv available, a plain cut section of wire or small rod can be used.

The top of the member 10, as shown in Figs. 1 and 2, determines the top of the layer of material 2. In constructing such layers, however, the gauge devices are often covered up and it is necessary to know their location and to see the tops thereof in order to properly construct the layer. In order that the location of the gauge device may be readily discerned, a flat member is provided comprising a piece of small flexible wire 11 which, as shown, is merely lapped around the lugs 8 and turned one or more times about the top of the member 10 and then projects above the layer 2.

= members 10 until the flanges 3 proper length. This is conveniently In operation, after the thickness of the layer has been determined, the workman takes a number of the/gauge devices and adjusts' the member 10 therein so as to give the done by merely placing the members between two boards which are spaced apart a'distance equal to the thickness of the layer tobe poured. The operator merely extends the and 5 touch one board and the end of the member 10 the other, and then quickly tightens the bolt 9 with a screw driver. The gauge members are then placed in properly spaced position.

' usually about four feet apart on the surface which is to receive the layer of material. The layer of material is then poured and leveled off in the usual manner so as to be flush with the top of the members 10. If the gauge devices are'covered up their location will be indicated by the members 11 and it can thus be quickly ascertained whether the layer is properly leveled. After the layer is completed, and while the material; is still soft, the ends of members'll can be bent downward into the layer of material and will be covered by the grout and semi-liquid portions of the layer and thus concealed. gauge devices remain permanently in the layer,'take up small room therein, present a very small portion visible atthe top and really act as a reinforcing means for the layer. The top of the gauge device which is exposed, is furthermore hard and will not wear down to form an objectionable hole in the layer. It will, of course, be understood If, however, the

The

that if the gauge device is to be used in a layer of street paving, the same will be placed upon top of the dirt or other which is to support the concrete.

The members 10 are sometimes adjusted be disposed some distance below the top of the layer, as shown in Fig. 3. In such use, a bar 12 is used having the small holes 13 therethrough through which the members 11 are adapted to project. The bar 12 thus rests on the top of members 10 and the layer of concrete 14 will extend to the top of the bars 12. The gauge devices are placed in posiion, as before described, and the bars 12 which are preferably tapered in cross section toward their lower edges, are placed thereon. The layer of concrete is then leveled off by drawing a bar along the top of-the bars 12. After the layer is thus leveled the bars 12 are lifted and the small grooves formed thereby are either left in the layer or the same may be filled.

In the form shown in Fig. 4, short openended cylinders or thimbles 15 are secured to one side of a bar 16 by small headed and nutted bolts 17. After the gauge devices are in place, the bar 16 is sition with the thimbles 15 surrounding the upper ends of the members 10, the bolts 17 resting on said members. The layers of material 18 can then be leveled by drawing the bar 19 along the tops of the bar 16 after which the bar 16 may be lifted and the spaces left thereby filled in, if desired.

In Fig. a portion of concrete floor shown as 20 supported upon the member 21 constituting gauge device shown in this figure is the same as that shown in 1. and 1 comprising the parts 3 to 9. The member 22 is used which replaces the member and this memher is shown as a wire or rod clamped in the extensions 8. Said wire or red, extends downwardly through the aperture in the base portions 3 and 5. and through an aperture in the member 21. The top of member 22 is embraced by thimbles 30 similar to thimbles in Fig. 4which are held in place on bar 12 by screws 29 similar to screws 17 in Fi g. 4. When the floor is formed, the lower 1d of the wire or rod 22, will merely hang down through the member 21. In such floor structure,.beams 28 are often usedwhich ex tend below the floor 20. It is frequently desired to build a ceiling layer 23 of concrete or other material in position to extend between the lower edges of the beams 28 so that a continuous surface of ceiling will be formed, thus concealing the spaced beams. One common form of such ceiling is shown in Fig. 5 and constitutes the layer of concrete 23 secured upon metal lath or fabric 2 1,

which fabric is supported upon spaced members commonly formed of small channel bars.

These members 25 have hitherto comlayer placed in pomembers embedded in the floor 20. With applicants construction, the portion of the member 22 which was left hanging below the floor is used to support the members 25 and is simply bent around the same and twisted upon itself thereabove, as clearly shown in Fig. 5. floor 20' is in place and set, the form boards 21 can be removed from below, as the hang-- ing lower ends of the members 22 will readily pass-through the apertures in said boards. Fig, 6 clearly shows the aperture or. hole through the base flanges 3 and 5 of the gauge device. I

A modified form of the gauge device is illustrated in the Figures 7 to 9 In thisform, the gauge device is provided with a semi-ey lindrical trough-shaped portion 26- of the same structure as the portion 7 shown in Figs. 1 and 2. The upper end of this portion is provided with forwardly extending por 'tions- 27' formed into substantially circularshape as shown inFig. 9 and provided with corrugations or roughened surfaces at their sides. lVith this structure, the member 10 or the member 22' will merely be pushed between the portions 27 and will frictionally be held in place. This structure, therefore, does not use the headed and nutted bolt 9 as the clamping means for holding such members in place.

From the above description, it is seen that applicant has provided an extremely simple and efiicient gauge device and one which has a high degree of utility for the purpose intended. The device is easily and inexpensively made, the same being stampedout and bent in one operation into the form shown. The members 10 are, of course, easily secured at small expense. The parts being of metal the same will not soon decay and leave an obdevice is quickly and easily adjusted and placed in position. The base portions 3 and 5 extend at-eac'h side of the-device giving stability thereto and insure that the device will not be easily toppled over.

It will, of course, be. understood, that various changes may be made in the form, details and proportions of the parts without departing from the scope of applicants invention, which, generally stated, consists in the matter shown and described and set forth in the appended claims.
